Seismic Risk Assessment and Retrofitting With Special Emphasis on Existing Low Rise Structures 2009
Soil-Structure Interaction Array(s)
State-of-the-art practice and analytical approaches require, when warranted, the
structure-foundation system to be represented by mathematical models that include
the influence of the sub-foundation media. In many cases, under a specific geotechnical
environment, certain structures will respond differently than if that structure
was built as a fixed based structure on a very stiff (e.g. rock) site condition. This
alteration of vibrational characteristics of structures due to soil-structure interaction
(SSI) can be both beneficial and detrimental for their performances. To date, the
engineering community is not clear about the pros and cons of SSI.
